This paper describes a fast non-linear algorithm which is capable of enhancing passive mm-wave images beyond their diffraction limited resolution from a knowledge of the imager point spread function. It is similar to the error energy reduction method of Gerchberg but may be applied to a general scene with no well defined spatial extent of known zero intensity. It was developed as a near real time algorithm that could be implemented in imager hardware.
